Definitions

  • the invention relates to a method for creating an underground tube. Furthermore, the invention relates to a device for carrying out this method.
  • the term subterranean tube is here and below also generally meant an underground cavity.
  • the tube or cavity is a connecting tube between a well and a tunnel tube. In mechanical tunneling, it is often necessary to connect a completed tunnel tube via connecting tubes or cross passages with a shaft structure, in particular with a caisson.
  • the connecting tube serves, for example, as a rescue passage in emergencies.
  • the creation of the connecting pipes is normally carried out under the protection of ground freezing due to the difficult geological and hydrological conditions, see e.g. DE 64556 C.
  • the frost created by the ground freezing process ensures that the soil above the construction site is effectively supported, thus ensuring the static load-bearing capacity during the construction period.
  • a groundwater foreclosure of the site is achieved with the frost body.
  • frost bodies distributed from a shaft in particular from a caisson
  • the caisson wall In order to remove the high loads resulting from earth pressure and water pressure, the caisson wall usually has to be highly reinforced frame-like.
  • the large number of icing holes leaves little room for the arrangement of an effective reinforcement in the horizontal and / or vertical direction. This is especially a special problem if an elaborate reinforcement is necessary in the area above and below the connection opening of the caisson.
  • the reinforcement of the shaft wall or caisson wall is adversely affected in the known measures by the introduction of a large number of icing. Similar problems arise when the icing lances have to be made out of a tunnel.
  • the invention the technical problem of providing a method of the type mentioned above, with which an underground tube can be prepared using a Bodenvereisung and in which the above-described problems can be avoided.
  • the invention is still the technical problem of providing an apparatus for performing this method.
  • the invention teaches a method for creating a subterranean tube, wherein before creating the tube in at least part of the environment of the tube temporarily at least one frost body is generated by ground icing.
  • This method is characterized in that an icing medium for generating the ground icing is passed through a pipe arranged in an already existing wall, which pipe runs along the outer surface of the wall. Subsequently, the tube wall can be made in the protection of Bodenvereisung.
  • the tube is meant in particular a connecting tube between a shaft and a tunnel.
  • the connecting tube can also be created between two tunnels or between two shafts.
  • the inventive method is particularly suitable for shorter distances between the two spaces to be connected through the tube.
  • the tube according to the invention preferably serves as a connecting tube for connection to a shaft or to a shaft opening in a shaft wall, in particular in a box wall.
  • a single continuous frost body can be generated, or else a plurality of adjacently arranged or spaced apart frost body sections.
  • existing wall means, in particular, a wall with a defined surface extending from the adjacent floor or ground different.
  • Existing wall means in the context of the invention, especially an artificially created wall, preferably a shaft wall, preferably a box wall.
  • the wall may also be a tunnel wall, which is formed in particular by tubbing.
  • the icing medium is passed through a pipeline extending at least along a part of the circumference of the tube or at least along a part of the circumference of the connection opening in the wall and that a frost body extending over this part of the tube circumference is formed ,
  • the pipeline extends at least along 40%, preferably at least along 50% and very preferably at least along 60% of the circumference of the tube or the connection opening.
  • the pipeline extends over the entire circumference of the tube or the connection opening. It is thus a circulating pipeline.
  • as few supply lines and drain lines for the icing medium are connected to a pipeline.
  • only one feed line and only one drain line for the icing medium is connected to a pipeline according to the invention.
  • the pipelines according to the invention can also be referred to as icing loops.
  • the at least one pipeline is arranged in the outer wall of a shaft, which shaft is connected via the tube with a tunnel.
  • Exterior wall here means the above-mentioned, already existing wall. It is within the scope of the invention that this wall is a vertically arranged or substantially vertically arranged wall. In the above-mentioned preferred embodiment, it is a Querschlagan Kunststoff a tunnel to the shaft or to the shaft structure. If this shaft is connected to the tunnel via the tube, according to a preferred embodiment of the invention, at least one pipeline for the icing medium is also provided in the tunnel wall. The pipeline is then expediently arranged in the outer surface of the tubbings of the tunnel wall. This at least one pipe in the outer surface of the tunnel wall is according to a preferred embodiment in the sole region or in the ridge region of the tube to be made.
  • the shaft may also be a diaphragm wall pit.
  • the pipe is placed in the outer wall of a caisson, which caisson is preferably connected via the tube with a tunnel. It is then realized a cross-connection of this tunnel to the caisson.
  • the method according to the invention is used for a direct connection between a tunnel and the shaft.
  • the tunnel leads directly into the shaft and the tunnel section to be created in the region of the shaft wall forms the tube according to the invention.
  • the tunnel is connected in this embodiment in particular to a traversed shaft or caisson. Such a connection also takes place, for example, in station areas.
  • the soil icing is carried out as nitrogen icing and / or as brine compaction.
  • An embodiment of the invention is characterized in that in a part of the environment of the tube to be created at least one frost body is generated by means of at least one introduced into the ground icing. So it is a ground icing according to the prior art, which is usually worked with glazing lances. Expediently, a plurality of icing bores or a plurality of icing lances are provided next to each other in said region.
  • Such a conventional ground freezing can be carried out in the ridge area or in the bottom area of the tube to be created. It should be emphasized, however, that this conventional ground freezing is carried out only as a supplementary measure to the ground icing according to the invention.
  • the invention also provides a device for creating an underground tube, wherein at least one wall is provided in which a connection opening for a pipe to be connected to the wall is introduced or introduced, wherein in the outer surface of the wall at least one for the passage of an icing medium provided pipeline runs, which pipeline surrounds the connection opening at least partially.
  • the pipe surrounds the connection opening over at least 50%, preferably over at least 60% and very preferably over at least 75% of the circumference of the connection opening.
  • the pipeline is flush with the outer surface of the wall. According to this embodiment, therefore, the pipeline does not project beyond the wall.
  • the pipeline is preferably anchored in the wall, anchored for example by means of headed bolts in the concrete of the wall. It is within the scope of the invention that only one supply line and only one drain line for the icing medium is connected to the pipeline. These are preferably inlet pipes and drain pipes with a relatively small diameter.
  • the invention is based on the finding that with the icing method according to the invention, the strength or

  • at least one frost body 2, 3, 4 is temporarily generated in the vicinity of the tube 1 and over the circumference of the tube 1 by ground icing.
  • An icing medium becomes the Generating this Bodenvereisung passed through at least one arranged in an existing wall 5 pipe 6.
  • This pipe 6 runs along the outer surface of the wall 5.
  • the tube 1 can be made in the protection of Bodenvereisung.
  • the pipe 6 extends over the entire circumference of the tube 1 and the connection opening 7 in the wall. Consequently, a frost body 2, 3, 4 is formed over this entire circumference of the connection opening 7.
  • the pipeline 6 is in direct contact with the ground to be frosted.
  • the pipe 6 is flush with the outer surface of the wall 5 from. This can be seen in particular in the enlarged detail of FIG. 1.
